Congrats! I celebrated my honeymoon there as well - it's a magical place to celebrate your new marriage!
Some little tips:
-Wear the bride & groom mouse ears. We got lots of little unexpected extra magic things wearing them. Even if we hadn't, we would've had fun wearing them anyways.
-Be sure to get the "Just Married" free buttons, we wore those as well & had the same results as above.
-Book a nice dinner. We liked California Grille during Wishes. We were lucky enough to get a window seat - it's breathtaking. The music is piped in, it's such a beautiful view.
-Drive over to Port Orleans and take a horse & carriage ride around property.
-Head to the Boardwalk in the evening. We loved taking a romantic stroll around the loop.
-Spend one night watching Wishes from the beach at the Polynesian. It was fairly quiet on the beach far to the left of the castle, and we caught the water pageant too.
-Be sure any restaurant you go to knows that you are celebrating!
Have fun!!
